Apologies for stating the obvious but, if the card can't be read by your laptop or your camera might it be a problem with the SD card or the adapter? Does the mini SD work in anything else?Might be worthwhile just buying a new SD card as they're cheap enough?

It did cross my mind that it could be the card so I got a new adapter.

I just wondered if there was anyway to format it when nothing will register it.
